The NJM2068 is a high performance, low noise and dual op-amp designed for audio and precision applications. The IC offers improved noise performance, distortion, slew rate and gain bandwidth over traditional op-amps like the 4558 IC. In this article I’m sharing the information’s about NJM2068 Pinout, Equivalent and Applications.
This IC has very similar performance and commonly using in audio pre amplifiers.
RC4558
This is older one with lower performance and suitable as a basic substitute
OPA2134
Using in higher end audio op amp devices with low noise and distortion
TL072
This is a JFET input op amp IC and its is not a direct substitute in all cases but popular
LM833
Has similar performance and used in low noise applications.
